Specification of Letters Patent.

Patente'dfiune 5, 1909. 1909. Serial no. 470,323.

To whom it may concern." Be it known that We, JAMES M. GALLO- wsr and ALEXANDER "W. TREVOR, of Rock Island county of. Rock Island, and State of Illinois, have invented certain new and useful. Improvements in Tube Repairing Devices; and we hereby declare that the following is a full, clear, and exact description thereof, reference being had to the ac cprepanying drawings, which form part of this specification.

This invention reiates t0 means for repairing rubber tubes and the like, and is particularly intended for use in applying patches to the inner tubes of pneumatic tires; and the objects of the invention are to provide novel means for stretching the part the tube to which a patch is to be applied; to provide novel means for holding the patch against the tube until the cement is set.

I: subsidiaryobject of the invention is to provide a novel repair kit in the form of a, box adapted to contain all materials necessary to make such repairs. and also parts of the clamping device. when not in use, the upperpart of such box forming the tube stretching device; and the box cover forming part of the means by which the tube is stretched; and also the lower member of the clamp by which the patch is held to the stretched tube'until the cement has set.

lVe will. now describe the invention in detail with reference to the form illustrated in the accompanying drawings, and set forth 1n the claims the parts and combinations of parts foravhich protection is desired.

In the drawingsFigure l is a side View of: the repair kite in use for patching an inner tube; showing the tube stretched and the patch clamp. applied, .i-nfull lines; and showing in dotted lines the position of the parts preparatory to, stretching the tube. Fig. 2 is a plan view of Fig. l, partly broken. Fig. 3 is a sectional view on line 33, Fig. 2, showing the clamp disengaged in dotted lines. Fig. 4 isa detail sectlonal V ew.

In the embodiment of the invention illustrated in the drawings the tube stretching device is'compose'd of two plates or boards 1.1", the inner ends of whichare hinged together at 1 and the'euter ends-of these plates are provided with etainers to engagea tabe As shown each retainer comprises a rod 2 which is pivoted at one end to'a stud form a hook 2 adapted to engage a springcatch 3 fastened to the other corner of the plate as indicated in the drawings, so as to hold the retainer in closed position close against the outer end of the plate. The outer end of the plate is grooved as shown at 1 adjacent the retainer 2 to facilitate the clamping of the tube between the retainer and the edge of the plate. The outer end of each plate is provided with a similar clamp. The plate 1 is preferably longer than the other, and is provided on its sides with long staples or keepers 3 which are adapted to be engaged by the hooked ends -1 of a bail-shaped clamp 4: which is adapted to be arranged transversely of the plate as shown in the drawings. 1 The legs 43 of clamp 4: are preferably made sufficiently resilient to enable them to be sprung into or out of engagement with keepers 3. Through the center of this bail 4 is tapped a screw 4 which is adapted to engage the upper side of a 'prcsser block 5 which may be placed over a patch P on the outer side of the tube Clbaud may be clamped thereagainst with any desired pressure by manipulating the screw 4*. In repairing a tube the device may be operated as fol.lows:.The tube, indicated'at" T- in the drawings, is clamped at, a point ad jacent the plate to be patchedb'etween one of the retainers 2 and edge of plate 1. The plate 1 may be then raised to the position indicated in dottedlines in Fig. l and 'anotherportion 0f the tube, at the other side of the part to be repaired, is clamped between the otherretainer 2 and the edge of the plate 1. The'tubc may be doubled between the retainer and plate edge if necessary in order to cause the retainers to hold it securely. The plate 1 is thenlo'wered into alincment with the-plate 1, thereby stretching the tube t'autly over the plates; the patch P'is then applied over the hole, in the tube and cemented inthe usual manner; then the resser-block 5 is placed over the pitch and the clamp 4c is placed over the presser-bl'ock and its legs 4 sprung into engagement. with' the keepers 3 and the de sired pressure is then'applied,to the patch by manipulating the screw a. The parts are then left in this condition until the cement has set, and the patch properly secured to the tube. This operation can be performed very quickly, and while the cement 5 is setting the workman can attend to other matters.

IVe do not wish to be restricted to the specific constructionof parts shown in the drawings, as the invention can be embodied 1 -11 various equivalent mechanical constructions.

The invention is useful in repair shops,

and is also particularly designed for use of automobilists and bicyclists. And, for the 1 latter purpose, as shown in the drawings,

the plates 1, 1*, may form the top of a. box- 6, the plate 1 can be fastto the top of such box and the plate 1 form a hinged cover for the box, .such cover 1 being normally held closed. by a suitable catch as indicated at 6". The box is of such size that when not in use the clamp 1- and presser -block 5 can be placed therein; and also a supply of patches, and cement and other materials necessary for patching tubes can be carried in the box.

By having the 'plates 1, 1 hinged together they form an efiicient stretching device and hold the inner tube taut during the cementing operation. The tube is crimped by the retainers 2 into the grooves 1 so that it will m be securely held during the repairing operation. .The device'holdsthe tube under tension during the cementing operation and holds the patch securely upon the stretched tube; and the tube can be readily cleansed around the part to be repaired after. it is stretchedthus insuring thorough adhesion of the patch to the tube.

Having describ (1 our invention what we 40 claim as new and desire to secure by Letters Patent thereon 1s:

1. In combination, a support, means for stretching an article to be patched upon said I support, a clamp attached to said support, and a presser-block interposed between the clamp and the article.

2., In a tube repairing device, the combination of a su port, means for stretchin a tube upon sait support, a clamp detachably attached to said support, a presser-block intel-posed between the clamp and the tube, and a' screw in said clamp engaging said block.

3. In combinatiom'a. support, a pair of retaining devices connected therewith adapted to engage the article to be repaired, a spring clamp having its legs detachably connected with the side of said support, and a presserblock interposed between ""t'he" support and said clamp.

' 4. In a tube patching device, the combination of-a su )port, a pair of retaining devices connecte therewith adapted to engage In a tube repairing device, the combination of a pair of hinged plates, a tube retaining'device on each plate, a clamp member connected to the plates, and a presserblock interposed between the clamp and plates. substantially as described.

6. In a tube repairing device, the conibination of a pair of hinged plates, a tube retaining (lQYlCQ attached to the outer end of each plate, a spring clamp detach-ably enaged with one of the plates. and a presser block interposed between said clamp and said plate.

T. In a tube repairing device, the combination of a pair of plates hinged at their inner ends and each having a recessed outer edge, rods attmfhcdto the ends of each 80 plate, a bail-shaped clamp-member connected with the plates, a pressenhlock inter: posed between said clamp member and the plate. and a screw tapped. through the clamp member.

' 9. In a repair kit for pneumatic tribes, and the like, the combination of a box, a cover therefor comprising one fixed and one hinged plate, tube retaining devices attached to the outer ends of the box cover, a clampoverlying one ot'the plates, and a presser-block adapted to be placed between/- said clamp and the said plate and over the tube.

10. In a repair kit for pneumatic tubes and the like, the combination of a box, a cover therefor comprising one fi'xed and-one hinged plate, tube retaining devices attached to the ends of the box, keepers at the aide of the box, a clamp ada ted to en the keepers, and a presserlock adapts to be placed between said clamp and the tube, substantially as described.
